My invention relates to voice producing and controlling device for dolls and more particularly to a device for etfectivelyproducing voice sounds uttered by the mouth of a baby, or child, as used in connection with dolls. r

The object of my present inventionis to provide a voice producing and controlling device which will effectively produce pa-pa syllables and ma-ma syllables alternately.

A further object of the invention is to provide a voice producing-device for dolls which possesses, advantages in points of simplicity and efficiency, and, at the same time'proves itself comparatively inexpensive in cost of manufacture.

lVith the above and other objects in view, the invention consists in the novel features of construction, arrangement and combina tion of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

Fig. 1, is a View of a sound production device partly in sectional elevation and partly in side elevation in full lines. The dotted ;lines illustrate the device in two tilted positions.

Fig. 2, is a longitudinal sectional view of the device.

Fig. 3, is a front elevation of the air expelling head of the bellows that produces pa-pa syllables.

Fig. 4, is a front elevation of the air expelling head of the bellows that produces mama syllables. I

Fig. 5, is a perspective view of the apertured valve bar. I

Fig. 6, is a perspective view of the sound producing device.

In carrying out the aim of my invention, I employ a suitable fiber, or equivalent cylindrical tubular casing 1.- The wall of the casing 1 is provided intermediate its ends, preferably midway thereof, with a suitable voice or sound outlet opening 2 which is preferably covered by means of a suitable fabric screen 3 to seal the interior of the casing from foreign particles entering the Same and yet adm t a r W the interier of the casing for supplying the bellows hereinafter described. 1 I

Suitable closure caps 4 and 5 are suitably fixed to the ends of the tubular casing 1 andeach cap is provided with a centrally disposed elongnatedsocket 6 which is formed by-pr essing the cap material outwardly at that point. Y

The numeral'i represents a suitable flat metallic valve bar which is stationarily supported at each end by causing the reduced ends 7 of the bar to be received in-thecap sockets 6 so as to be disposed centrally of the casing l and running longitudinally thereof I with its center line thereof parallel with the wall of the case 1. v

Mounted .for alternate slidingmovement ably shaped metallic bellows air expelling heads8 and 9 to. whichis suitably fixed the upon the flat valve bar 7 are a pair of suit- 1 tained at the outer ends of the tube, but

within the same by applying an adhesive to the outer face of the bellows bagsadjacent the rings so as to cause thesame to adhere to the inner face of the tube 1.

The slidably mounted bellows air expelling heads 8 and 9 are provided with centrally disposed slottedopenings 14: and 15, respectively for receiving the stationary valve bar 7 upon which bar the bellows air expelling heads 8 and 9 are alternately slidable and free from possible rotary displacement thereupon. The bellows air expelling heads 8 and9 arefurther provided with the p the transversely slotted openings 18 and 19,

' respectively in their lower walls 20 and 21,

. air chambers 16 and 17 respectively having posed in the bellows air expelling head sections 24'and 25, respectively at the lower side of the valve bar receiving openings 18 and 19 of the bellows air expelling heads 8 and 9 respectively.

I The bellows air expelling heads 8 and 9 are provided with suitable sound producing reeds 26 and 27, respectively. The reeds 26 and 27 are suitably connected at their inner ends to'the inner Walls 28 29 of the bet I openings and 31, respectively.

The alternately slidable bellows air eX- polling head 8 is provided in the wall section 32 with a su table. air pressure relief opening 33 communicating directly with the air chamber 34 within the bellows bag 1 to produce sharp voice sounds. The alternately'slidable bellows air expolling head 9 is not provided with an air pressure relief opening for the bellows air chamber 35, but in lieu thereof, the wall section 36 of the air ex ellinp; head 9 is pro- "Vidfifl with a suitab e air pressure relief o 'ening 37 communicating directly with the air-chamber 17 within the bellows air expelling head 9 so as to cause soft voice sounds.

The 'valve bar 7 which supports the slidable bellows air expelling heads 8 and 9 is provided near one'en'd with the air pas sages 08 and 39 which cause the uttering of pa-pa voice sounds through the reed when the air outlet opening 18 in the lower wall of the-air chamber 16 of bellows air expelling head 8 passes the openings 38 and39 of the valve bar7, in its outward sliding movement thereon. "Opening 38 'is transversely disposed while opening 39 is longitudinally dispose-d and these openings are preferably elongated in shape. i

The valve bar 7 is'provided at its op posite end with the'air passage or openings 10 and 41 which cause the uttering of ma ma voice sounds through the reed when the air opening 19 in-thelower wall of the air chamber 17 of bellows air expelling head 9 passes the openingsAO and 41 of the valve bar 7 in its outward sliding movement there. on. The opening 40' is transversely disposed while opening 41 is longitndinaliy disposed and these openings are preferably elongated. 45

'Openings 38 and 49Qare transversely disposed to sharpen and make quicker the first pa and ma syllables respectively pro- I duced thereby while the openings 39 and 41 are longitudinallydisposed andelongated to draw out and lengthen the second pa and ma syllables, respectively produced there- The bellows air expelling heads 8 and 9 are slidably mounted independent of each other upon the valve bar 7 inopposed relation to each other, and so disposed and spaced with relation to each other that they will not come intocontact with each other when at their inner most positions, The air expelling heads of the bellows both slide in the same direction at the same time when the casing 1 is tilted in either direction, as indicated in dotted lines A and B in Fig. 1, so that while one bellows is producing pa-pa syllables when tilted to position des- -duce ma-ma syllables.

in the head wall 36 relieves the air pressure the sound of the reed,

ignated A, the other bellows which produces ma-ma syllables is filling with air to be compressed therein when the casing 1 is tilted in the opposite direction, designated B.

The operation of the sound producing and ward position upon the valve bar 7 causing the air to pass through the reed 26 into chain-f her 16 and through opening 18 and out of the valve bar openings 38 and 39' thereby causing the reed to produce pa-pa syllables. The opening 33 in the head wall 32 relieves the pressure within the bellows bag 10 so as to prevent the closing' of the reed and yet only relieve enough pressure to provide a sharp sound the reed in producing papa syllables.

WVhen the device is tilted to the opposite the reed 27 into chamber 17 and through opening 19 and out of-the valve bar openings 40 and 11 thereby causing the reed to pro- The opening 37 with the head chamber 17 suflicient to soften 27 in producing ma-ma syllables.

It will be apparent that when air is being compressed within the bellows bag 10. that the bellows bag 11 is taking in air.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.
